The demand for diatomaceous earth functional fillers in the plastic industry is very high. Due to the unique and excellent properties of Fengda diatomaceous earth functional filler, it can become a regulator, reinforcing agent, semi reinforcing agent, slow-release agent, and insulation agent for plastics. Diatomaceous earth has a small particle size, large specific surface area, porosity, low thermal conductivity, and good dispersibility. It can reduce pores and voids in plastics, making the mixing and shrinkage of plastics more uniform. Therefore, it can be filled in polymers such as polystyrene, polyethylene, polyvinyl chloride, aldehyde, phenolic plastics, etc. as an opening agent, diaphragm agent, slow-release agent, insulation agent, etc., to improve the stability, hardness, and rigidity of plastic products. It can significantly improve the toughness, rigidity, bending strength of products, enhance their heat resistance, dimensional stability, and other processing properties. It can partially replace other expensive fillers and additives, thereby improving market competitiveness.

The use of Fengda diatomaceous earth functional fillers in the paper industry has the following advantages: 1) the light shielding properties of paper products are significantly improved; 2) Diatomaceous earth has less wear on paper, making paper products more uniform and flat; 3) Reduce pulp and increase filler usage to lower production costs; 4) Diatomaceous earth has good oil absorption, which improves the pigment firmness of colored paper; 5) When filling neutral paper or cardboard, Fengda diatomaceous earth functional filler can improve their tightness.

At present, the usage of diatomaceous earth functional fillers in the coating industry is rapidly increasing. The addition of Fengda diatomaceous earth functional filler in water-based coatings can greatly improve the system's reinforcement, transparency, thixotropy, leveling, insulation, and adsorption properties, significantly enhancing the coating's stain resistance, scrub resistance, adhesion, and anti settling effect. It can partially replace expensive titanium dioxide and reduce the amount of other additives, significantly reducing the production cost of coatings.

Fengda diatomaceous earth functional filler ink has good printing performance and stability. Due to the small particle size of this product, the printing network is complete and the coverage is strong. Diatomaceous earth, as a filler, can also exhibit good ink absorption during ink printing, which helps to improve the fast drying performance of ink. When diatomaceous earth is used as a filler for ink, it not only has the function of a general ink filler, but also has the advantages of good stability, high glossiness, strong adaptability, and does not affect the drying characteristics of the ink. Moreover, it is cheap and can reduce costs. Used for high-end ink, it can improve the adhesion of ink, reduce the wear of ink on machinery, and is suitable for high-speed printing.
